CCAMLR

Following discussion at the Scientific Committee in 2016, we propose a process for independent review of CCAMLR integrated toothfish stock assessments based on the process used by the Center for Independent Experts (CIE, NOAA), and the benchmarking process used by ICES.

The Southern Ocean Observing System (SOOS) has developed a number of networks and products of importance to the work of CCAMLR. Through this paper, SOOS seeks to update SC-CCAMLR on this progress and invite collaboration towards delivery of networks and tools that will benefit both communities. SOOS encourages CCAMLR delegates to communicate with, and be involved in the SOOS regional networks that are coordinating and enhancing observational data collection and delivery. SOOS invites CCAMLR to contribute directly to the Database of Upcoming Expeditions to the Southern Ocean to facilitate international scientific collaboration. Further, SOOS requests input from SC-CCAMLR on the “SOOSmap” data discovery tool, including discussions on key data layers of interest to, and potentially provided by CCAMLR. These requests will form the foundation for discussions at the proposed joint workshop between SOOS and SC-CCAMLR (SC-CAMLR-XXXVI/BG/15).

This paper presents the latest developments in models for Crozet following the more recent ones (Sinègre & Duhamel, 2016) with an updating of input data from the more recent years (up to 2016/17 season) and a reassessment of stocks taking into account the previous remarks of the WG-FSA meetings.

This paper presents the latest developments in model of Kerguelen with an updating of input data from the more recent years (up to 2016/17 season) and a reassessment of stocks taking into account the previous remarks of the WG-FSA meetings.

In 2017, a bottom trawl survey (PoKer 4) was undertaken at Kerguelen Islands (Division 58.5.1) to collect information about the size distribution and the biomass status of mackerel icefish, Champsocephalus gunnari. Data from this random stratified trawl survey was used for a short term assessment of C. gunnari on Kerguelen EEZ. The standard CCAMLR methods were used to provide potential yields, a catch limit of 3081 t is recommended for 2017/2018 and 2753 t for 2018/2019.
